<DL>
<DD>Encode the uncompressed source image associated with this compressor
instance and output a YUV planar image to the given destination buffer.
This method uses the accelerated color conversion routines in
TurboJPEG's underlying codec to produce a planar YUV image that is
suitable for direct video display. Specifically, if the chrominance
components are subsampled along the horizontal dimension, then the width
of the luminance plane is padded to the nearest multiple of 2 in the
output image (same goes for the height of the luminance plane, if the
chrominance components are subsampled along the vertical dimension.)
Also, each line of each plane in the output image is padded to 4 bytes.
Although this will work with any subsampling option, it is really only
useful in combination with <A HREF="../../../org/libjpegturbo/turbojpeg/TJ.html#SAMP_420"><CODE>TJ.SAMP_420</CODE></A>, which produces an image
compatible with the I420 (AKA "YUV420P") format.
This method uses the accelerated color conversion routines in TurboJPEG's
underlying codec but does not execute any of the other steps in the JPEG
compression process. The Y, U, and V image planes are stored sequentially
into the destination buffer, and the size of each plane is determined by
the width and height of the source image, as well as the specified padding
and level of chrominance subsampling. If the chrominance components are
subsampled along the horizontal dimension, then the width of the luminance
plane is padded to the nearest multiple of 2 in the output image (same
goes for the height of the luminance plane, if the chrominance components
are subsampled along the vertical dimension.)

* components are subsampled along the horizontal dimension, then the width
* of the luminance plane is padded to the nearest multiple of 2 in the

* underlying codec but does not execute any of the other steps in the JPEG
* compression process. The Y, U, and V image planes are stored sequentially
* into the destination buffer, and the size of each plane is determined by
* the width and height of the source image, as well as the specified padding
* and level of chrominance subsampling. If the chrominance components are
